Heating, ventilating and air conditioning (HVAC) systems typically include a variety of different components to provide a complete heating and/or cooling cycle. These systems may include, for example, heat pumps, furnaces, compressors, fans, heat exchangers, one or more air ducts, air handlers and the like. These systems typically have a control device to receive control signals to operate the system to condition a space by heating or cooling the space to a desired temperature. The control devices of the system are generally inter-connected to a thermostat that sends electronic signals to the various control devices based on a comparison between a desired temperature for the conditioned space and the actual temperature of the space.
Efficient operation of these HVAC systems can be very difficult due to the multiple variables that effect operation thereof. For example, humidity, temperature, pressure, cleanliness and the like can all effect performance of the HVAC system.
